Exclude abandoned IVR calls from the inbox

Business problem

Currently, calls appear in the inbox even when a caller hangs up while navigating the IVR menu. This clutters the overview with unanswered calls from callers who never actually tried to reach an agent.

Desired outcome

Calls where the caller hangs up within the IVR routing should not appear as a conversation in the Trengo inbox. A call should only become visible in the inbox when the caller has successfully navigated the menu and the connection to a team or agent is established.
